Mineralogical properties of basic clay minerals (kaolinite, illite, and montmorillonite).
| Clay mineral | Structure | Interlayer bond/intensity | Isomorphous substitution | Shrink-swell | CEC (meq/100 g) | LL (%) | K (m/s) |
| Kaolinite (1 : 1 clay mineral) | | Hydrogen, strong | Low | Very low | 3–15 | 30–75 | 10−5–10−7 | Illite (2 : 1 clay mineral) | | K-ion, moderate | Moderate | Low | 10–40 | 60–120 | 10−6–10−8 | Montmorillonite (2 : 1 clay mineral) | Van der Waal, very weak | High | Very high | 29–150 | Up to 900 | 10−7–10−9 |
